Revox A77 Renovation Part 1: investigation with case removed

PLEASE COMMENT BELOW if you can contribute any knowledge or insights to this project. This is the first video in series about testing and renovating a Revox A77 vintage reel to reel tape recorder. In this episode, I remove the wooden case, inspect the mechanism inside and examine the input/output panel. This panel looks like a non-factory customisation to support XLR-type connectors for use in broadcast facility or recording studio . Thanks for watching!
